BBSAK for Z10

That's a great question and I don't think I've seen one yet, but I'm gonna contact the developer and see if he has one or is working on one currently. It would definitely come in handy but may not be possible due to how BB10's OS actually works.

There is nothing like that for the BlackBerry 10 yet. Those tools manipulate the OS in ways that are not possible yet on BB10. I doubt you will see one anytime soon, but that's not to say it could never happen.
